The complete Board Game Counter.
It looks likes a single dice (i.e. die), but it is not. In some parts of the United States, playing with dice is considered gambling and should not be discussed in a public school in the presence of minors. So remember, this is a board game counter, like you would use to play Sorry or Candy-Land. Any resemblance to a dice game is purely coincidental.

This slide reviews the theory of operation for the Board Game Counter.
The Analog Section produces a dampened square wave that “rolls” the count and slowly stops.
On every pulse of the clock, the Sequential Logic Section increments a binary count from 1 to 6, then repeats.
The Combinational Logic Section encodes the binary count into the die’s seven “dots.”
